如何从 Delphi 中的 TScrollBox 中获取选定的表单？
我正在滚动框中动态创建一些表单。
当我单击创建的表单时，我想获取存储在该特定表单中的一些值到父表单。这可能吗？如果是这样，我该怎么办？
我希望这听起来不会令人困惑。这是我正在做的事情的屏幕截图。
I am creating some forms inside a scroll box, dynamically.
When I click on a created form I want to get some values that are stored in that particular form to the parent form. Is this possible? If so, how can I do it?
I hope it doesn't sound confusing. Here is a screen shot of what I am doing.

创建表单时，将其索引存储在其 Tag 属性中。我将对动态表单的引用存储在数组或列表中以便稍后访问它们，但即使您只是使用滚动框作为所有者创建它们，它们也会有一个滚动框的索引。Controls[x]
我猜您在表单/标签/图像上有（或需要）一些事件作为 onlclick 事件，以便您的用户可以选择一个表单，然后您可以更改背景色（或标签颜色）以显示该表单已被选中。此时，您可以更新父滚动框中的 Tag 属性以匹配表单的 Tag （我假设您将表单存储在数组或列表中）。然后，您可以使用该标记作为“选定索引”属性。
从那时起，从索引访问表单成员就变得相当简单了。
When you create the forms store an Index to them in their Tag property. I'd be storing references to dynamic forms in an array or list to access them later, but even if your just creating them with the scrollbox as the owner they'll have an index for scrollbox.Controls[x]
I'm guessing the you have (or need) some event on the form/labels/images as an onlclick event so your user can select a form, then you can change the backcolor (or label color) to show that the form is selected. At this point you could update the Tag property in the parent scrollbox to match the Tag of the form (I'm assuming your storing the forms in an array or list). You can then use the Tag as a "Selected Index" property.
From that point it's fairly trivial to access the forms members from the index.
